Abstract

ABSTRACT: The reduction of the interlayer in hybrid white organic light-emitting diodes (WOLEDs) provides a potential for improving the device efficiency. Reported herein are non-interlayer hybrid WOLEDs prepared using a mixed host for the blue-fluorescent-emitting layer. The proposed device exhibits high efficiency with the maximum external quantum efficiency up to 17.1%, and stable colors. Moreover, the effect of the interlayer on the device lifetime was demonstrated.
